Interleukin 25

IL-25, IL-17E, Interleukin-25

The protein encoded by this gene is a cytokine that shares sequence similarity with interleukin 17. This cytokine can induce NF-kappaB activation, and stimulate the production of interleukin 8. Both this cytokine and interleukin 17B are ligands for the cytokine receptor IL17BR. Studies of a similar gene in mice suggest that this cytokine may be a pro-inflammatory cytokine favoring the Th2-type immune response. Alternative splicing results in multiple transcript variants.

RECENT FINDINGS: The last few years have seen crucial advances in how innate immune cells such as innate lymphoid cells group 2 and airway epithelial cells and related molecular pathways through organismal proteinases and innate immune cytokines, such as thymic stromal lymphopoietin, IL-25, and IL-33 contribute to allergy and asthma.

Experiments in mice and humans have demonstrated requirements for the epithelial cytokines IL-33, thymic stromal lymphopoietin (TSLP) and IL-25 in the activation of ILC2s, but the sources and regulation of these signals remain poorly defined.

Moreover, the expression of innate cytokines such as IL-25 and IL-33 in nasal epithelial cells were reduced and the expression of chemokines such as CCL24 (eotaxin-2), CXCL1 and CXCL2 was decreased in the nasal mucosa, suggesting the underlying mechanism for intralymphatic administration of the OVA-FlaB mixture.

These ECs mount a prototypical response made up of chemokines, innate cytokines such as interleukin-1 (IL-1), IL-25, IL-33, and thymic stromal lymphopoietin (TSLP), as well as the alarmins uric acid, ATP, HMGB1, and S100 proteins.

findings indicate that Act1 expression in T cells is required for cellular and humoral Th2-mediated allergic responses and the development of airway hyperresponsiveness, in part, through Act1's function in IL-25-induced development of Th2 T cells
